Yes, but depending on the origin you play the stronger the temptation is. For example, I don't see why Astarion would refuse the tadpole. Also, there's Durge, who is a slave to Bhaal without the tadpole. So you could try to play as a "good" Durge who uses the tadpole to get rid of Bhaal. And let's be real, even as a good paladin the guaranteed critical once a day is pretty tempting to me.

I agree 1000% on the dreams though. One of my earlier complaints is that the dreams should be available to everyone not just those who abuse the tadpole.

However, your point about the conquest dreams is not the fault of Daisy but rather the terrible origin system of this game. The origin system itself doesn't allow you to flesh out the goals and dreams of your character. You're right, my evil character doesn't want to burn down the city but rather rule a shadowy council behind the scenes.

Lastly, what might make Daisy simply better than the Emperor is that it wasn't shoehorned in there at the last second.
